Google Maps recently received an update adding multiple new social features for the popular mobile mapping service. The update included some minor performance enhancements along with the ability to post ratings for places directly to your personal Twitter account. In addition you will be able to “ping” friends to request check-ins. Per the Google Mobile Blog, both parties utilizing the mapping service must be on version 5.2 to benefit from this. Let us know what you think of the new functionality in the comments below. Head on over to our apps database for the download.
